So if I import into Lightroom using the convert to DNG option, I'll be able to then edit the DNG file in LR? (or PS?) Surely that isn't optimal as the conversion to DNG pre-supposes a knowledge of the way the RAW file has been constructed? But if not optimal, good enough until ACR is updated?

i have just bought a G10 (import from the USA). The enclosed software is DPP 3.5 which installs okay on my Macpro (10.5) but DPP will not open the raw files - it just hangs. Do I have to wait until Apple add the G10 to their raw processing engine or am I doing something wrong.

Any help on this subject would be very much appreciated.

No, Apple support for the G10 would only apply to Apple software, such as iPhoto, Aperture.

Because my interest in the G10 is heavily weighted toward low light shooting, I took a set of test shots at the local dealer's at ISOs from 100 to 1600. Using the DNG converter, I imported them into Lightroom, and was totally taken aback at how much noise I'm seeing, even at 200. Here's a link to the DNG file: IMG_0014.dng.

DPP is applying a pretty significant amount of NR even when NR is supposedly off, or

DNG somehow amplifies noise, or

importing DNG into Lightroom somehow side-steps it's own level 0 NR.

Notice that this shot is if anything slightly over-exposed, so it's not is if under-exposure is responsible for excess noise.

I'd appreciate any input as to whether there's something amiss with my test shot, and if not, as to what's going on here. There seems to be two camps on this issue: one that even 200 ISO is seriously noisy and one that 400 is quite usable. Based on what I'm seeing, I'd have to side with the first camp.

Can't say whether that's all you are seeing, but if LR doesn't recognize a camera (and at the moment, it won't recognize a G10), it is very conservative about its default settings. So its quite possible that NR is set quite low.
